Niall posted a few selfies to his Instagram account, and they look a lot prettier and more artistic than our own attempts usually end up.

Alongside Will, he looks almost quizzical with a cocked eyebrow, while his new friend appears to be in deadpan, Ron Burgundy-mode.

He wrote: "Here he is! The only and only ! Will Ferrell !"

However, the Story of My Life singer seemed even more chuffed to have met Will's co-star Paul Rudd - who reprises the role of Brian Fantana in the sequel - who was apparently a "pleasure to work with".

He said: "What a super great guy ! Pleasure to work with!honour to meet! will never forget tonight! (sic)"
